What is the mass of a shopping cart that is pushed with a net force of 10 n to accelerate at the rate of 0.5 m/s2?

Actualy the correct answer is going to be 20kg. And this how i got it. All i did was 10 divided by .5 and i got the answer.

Please mark brainiest please.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
